This doesn't really apply to Lagwagon, and NOFX probably had more because there's more of a demand for it, but the number for Propagandhi seems to reference the release number of the record (FAT 506).
Looking for the following:
Jawbreaker - Live 4/30/96
The Lawrence Arms - The Greatest Story Ever Told (maroon)
NOFX - Drowning Roses Split 7" (black or red)
NOFX - OX Fanzine Split 7"
NOFX - The Longest Line (grey)
NOFX - Fuck the Kids 7" (green)
NOFX - The Decline (clear)
Those NOFX records would come really close to completing my collection.
